Insect bites and stings can cause an immediate skin reaction. The bite from fire ants and the sting from bees, wasps, and hornets are most often painful. Bites caused by mosquitoes, fleas, and mites are more likely to cause itching than pain.
Insect and spider bites cause more deaths from venom reactions than bites from snakes.
In most cases, bites and stings can be easily treated at home.
Some people have extreme reactions that require immediate medical treatment to prevent death.
Certain spider bites, such as the black widow or brown recluse, can cause serious illness or death. Most spider bites are harmless. If possible, bring the insect or spider that bit you with you when you go for medical treatment so it can be identified.
Symptoms depend on the type of bite or sting. They may include:
Some people have severe, life-threatening reactions to bee stings or insect bites. This is called anaphylactic shock. This condition can occur very quickly and lead to rapid death if not treated quickly.
Symptoms of anaphylaxis can occur quickly and affect the whole body. They include:
For severe reactions, first check the person's airways and breathing. If necessary, call 911 and begin rescue breathing and CPR. Then, follow these steps:
General steps for most bites and stings:
Remove the stinger by scraping the back of a credit card or other straight-edged object across the stinger. Do not use tweezers -- these may squeeze the venom sac and increase the amount of venom released.
Wash the site thoroughly with soap and water. Then, follow these steps:
Use the following precautions:
